32mm Thread Shaft Worm Gear Motor − 81mm Type Model NFP-JGY-370-M6 / M8

For hooking this motor up to projects in a reversible but still dependable manner. They can be a little pricey for me but are worth it, i can dissemble these motors to see how they work, and put them back together easily, there are fairly strong magnets in there, finally get the motor mount where I wanted it for one project to.
